SHREDDING-MACHINE.

Application filed February 27, 1912. Serial No. 680,254.

To all ecirom it may concern Be it known that I, Smbnnn T. STUVER, acitizen of. the United States, and a resident of Tacoma, in the countyof Pierce and State 5 of Washington, have invented a new and ImprovedshreddingMachine, of which the following is a full, clear, and exactdescription.

My invention relates generally to vegetable shredders and moreparticularly to a new and improved device involving few parts of simpleconstruction, the rotatable element therein being removable whereby asimilarelement, but one providing for a different degree of shredding,may be in serted.

The principal object of my invention is to provide a vegetable shreddercomprising a suitable casing with a rotatable shredding element mountedtherein, this shredding element taking a plurality of forms wherebydifi'erentedegrees of shredding may be obtained. 1

Other objects and advantages of thein- '55 wen-tion will appear as thedescription thereof procemie new and-useful featu es be ing pointed outin the appended claims.

Reference is to be had to the accompanying drawings forming part of thisspecification, inwhich similar characters of reference denotecorresponding parts in all theviews, and in which- Figure 1 is aperspective View of the shredder in operative position; Fig. 2 is avertical sectional view thereof; Fig. 3 is a vertical .sectional view atright angles to Fig. 2; Fig. 4 is a perspective new of a modifiedform ofshredding element.

As shown in the drawings, the device comthereo-f and'adjacent one end,the lug3 being provided with a transversely movable 'bolt 4 whereby thedevice may be positioned thr'eaded opening 10 adjacent one end thereofin engagement with the shaft 8, whereby turning of the handle will turnthe shaft.

Secured to the upper end 6 of the standposition by means of bolts andnuts 12, the

Specification of- Letters Patent,

prises any suitable standard 1 having a pl.u-. rality of lugs 2, 3,extending transversely,

adjacent the edge portion of any support 5.

ard 1 'is the casing 11, preferably .held in' Patented Oct. 20, 1914.

upper portion of this casing being provided with an opening, there beinga hopper 13 adacent thereto adapted to receive vegetables or othersubstances. This casing member 11 is preferably frusto-conical inconstruction, one end thereof being closed' by the member 14 which liesclosely adjacent the upper end 6 of the standard 1. The other end of thecasing member 11 is open, this open end being the end of larger diameterwhereby the revoluble shredding elementlo or 15 may be convenientlyplaced in position.

The inner end of the threaded shaft 8 is provided with a frusto-conicalsupporting member 16 having a number of lugs 17 on the outer side andextending normally therefrom, these lugs being adapted to be received inthe openings 18 positioned adjacent the smaller end of the shreddingelement 15 or 15. 1

The shredding element 15 is preferably of frusto-conical formation andis providedwith a number of outwardly bent blades 19 which may be of anydesirable construction, the

othernslrge ldii ig elementlb being provided with continuouslmhides-20,--the The hopper 1 3 is designed to receive a I suitable number ofvegetables or other substances which are to be shredded, turning of thehandle 9 rotating the shredding elements and bringing the outer edges ofthe blades into engagement with the vegetables whereby suitable portionsare removed from them which pass through the openings in the elementsadjacent the blades, theshredded material leaving the open endof theelements and being received in any suitable receptacle. If so desired,the hopper 13 may be provided with a movableelement 21 in the'na ture ofa cover adapted to be. pressed down' against the vegetables or, othersubstances and bring them into firm engagement .with the blades of therotatable shredding ele ments.

The shredding elements shown differ from. each other only in theparticular form of .blades provided thereon, it being obvious that theconstruction and operation of the device remain the samewhateverthe formof blade; the blades are easily changed by removing the handle 9 andwithdrawin the circular supporting member 16, after w 'ch the shreddingelement thereon may be taken oil and the other form placed in position.

' Having thus described my invention, I

I claim as new, and desire to secure by Letters Patent: 4

1. In a shredding machine, the combination of a conical casin having itssmaller end closed, and a, shred ing element mounted in'the casing, saidelement comprising a disk-like-lmeinber having a frusto-conical flan eand a centrally arranged shaft projecting therefrom, said flange beingprovidedwith external pins, and 'an open ended frusto-conical tubularbody having peripheral bladesvand pi'ovided with L-shaped openings atits smaller'end, the horizontal portions of the openingsbeing adjacentthe smaller end ofthe body and the longitudinal portions extending inthe direction of the opposite larger end of said body, the smallerendofthe body fittin upon the said flange with the pins thereo engagin itsslots and its end closely adjacent the c osed end of the casing.

2,111 & shredding. machine, the combinav tion of a support, afrusto-conical casing having its smaller end closed and secured to thesupport, the closed end of the casing and support having registeringopenings,adisk rlike member having a frusto-conical flange and a centralshaft mounted in the openings of the support and easing, the said flangebeing provided with pins on-its periphery, and a frusto conicaltubularbody open atbothends and provided with peripheral blades and initssmaller-end with L-shaped openings,.the said smaller end of the bodybeing closely adjacent said closed end of the casing andfitting on thesaid flange with the pins of the flange projecting into the openings ofthe body, whereby'the body can be readily attached to or removed fromthe disk-like member and when attached and the parts are in position theEVA C. STUVER.
